What type of cutter is used primarily to create flat surfaces in machining?

• A. Drill Bit
• B. Face Mill
• C. End Mill
• D. Reamer

Answer: (B)

The face mill is specifically designed for creating flat surfaces during machining operations. It consists of multiple cutting edges that are mounted on a rotating body and can cover a large area, allowing for efficient material removal to produce a smooth, level surface. The geometry of the face mill enables it to work on both horizontal and vertical surfaces, making it versatile for a variety of machining tasks. In contrast, a drill bit is primarily used for creating holes and is not suited for generating flat surfaces. An end mill is versatile and can also be used for milling flat surfaces, but it is more commonly applied for producing complex shapes, contours, or for plunging actions. A reamer is designed to refine the sizes of pre-drilled holes, achieving a higher degree of precision, but it cannot create flat surfaces as its primary function. Therefore, the face mill is the most accurate choice for the task of creating flat surfaces in machining.
